In a vehicle seat system equipped with an active headrest mechanism () and a lumbar support (), a load-receiving part () of the active headrest mechanism () is positioned behind the lumbar support () as viewed from front of the seat. The vehicle seat system is arranged so that when a specified amount or more of load is applied from front of the seat to a lumbar support plate () of the lumbar support (), one end part of a plate support member () supporting the lumbar support plate () exits from an insertion hole () provided at a side frame () to disengage from a seatback frame (), and the disengaged end part of the plate support member () then abuts on the load-receiving part ().

Vehicle seat system

An instrument panel of a vehicle mounts a cluster gauge and is formed with an opening through which a collapsible steering shaft projects. A steering end cover, formed as a hollow shell, is generally cylindrically shaped and covers an end portion of the collapsible steering shaft projecting above the instrument panel. A guide member, provided so as to overlap the opening, has a surface for guiding the hollow shell to sink or telescope into the opening when the collapsible steering shaft axially collapses during a front end, head-on collision.
